Fig. 1. Selective diversion of host cell lipids. Coverslip-grown host cells were
incubated with fluorescent probes alone (hosts), infected with T.
gondii prior to the introduction of the probe (toxo+lipid), or labeled
with the probe before infection with T. gondii (lipid+toxo). Images
of live cells were immediately acquired by confocal microscopy. Single, 0.4
µm thick optical sections are shown. Cholesterol, NBD-cholesterol; PC,
BODIPY-phosphatidylcholine; PA, BODIPY-phosphatidic acid; C4C9, C4-BODIPY-C9.
Red emission in the C4C9 panels corresponds to excimer shift of highly
concentrated BODIPY. Intracellular parasites in the PC lipid+toxo panel are
indicated with asterisks. Bars, 20 µm (hosts); 5 µm (toxo+lipid,
lipid+toxo).
